so i just upgrade my gpu from a XFX 6770 to a MSI gtx 660. i run duel monitors 21.5 main 17 2nd the 17inch one is a old vga only plug so i run a adapter and the 21.5 is dvi. now with my old card when i turned it on they came on 2-3 sec apart and both would show the bio screen and both go they the windows splash screen. now with my new card only my 17inch one shows the bios screen and once it starts to boot into windows the 21.5 comes on and the 17 goes black till windows loads then there both on so far from my few hours of testing in windows all seems fine but id rather check with someone smart lol
